When I changed my sim I noticed the LTE setting was there. But now, a couple of days later it has disappeared. When Cellular Data is turned on, all I see is the option to tur Data Roaming on or off. Where did the other options go?
iPhone 8 Plus, iOS 12
I think it’s because it’s an unlocked iphone8 Plus model A1897, which is a gsm from AT&T, and it is not compatible on Verizon’s cdma network. That’s why the 4G and LTE options disappear in the cellular options menu.
While Verizon does use a CDMA network, that is their legacy network. The support LTE, and that is handled by a SIM. Did you contact Verizon about bringing your device to their network? They would be able to tell you about activating it. Verizon has supported bringing unlocked phones to their network since the iPhone 6S I believe. A call to Verizon Customer service would tell you if that model number is supported.
Check with your carrier. It is possible that you had a carrier file update that has changed those settings. The carriers are responsible for that setting.
